FI-DV 01 Professional Profile and Industries

The digital transformation is fundamentally changing the world of work. As an IT specialist in the field of digital networking, you design the infrastructure for Industry 4.0, smart buildings, intelligent logistics systems, and modern energy networks. This module imparts the fundamentals of your professional profile and the specific requirements of the key industries in which you will work.

The increasing networking of physical objects and systems requires specialized knowledge in network technologies, data communication, and IT security. You will acquire an understanding of the relationships between the physical and digital worlds and learn how to plan, implement, and operate robust, scalable, and secure networked systems.

Concepts and Background

Industry 4.0

The fourth industrial revolution, characterized by the networking of production systems through cyber-physical systems, the Internet of Things (IoT), and cyber-physical systems (CPS). The goal is the smart factory with flexible, self-organizing production processes.

Smart Building

Intelligent buildings optimized through networked systems for automation, energy efficiency, and comfort. Technologies such as Building Management Systems (BMS), IoT sensors, and KNX protocols enable control of heating, ventilation, lighting, and security.

Logistics 4.0

The digital transformation of the logistics industry through technologies such as RFID, GPS, IoT, and AI. Real-time tracking, automated warehouse management, and networked transport chains enable a transparent and efficient supply chain.

Energy Networks

Smart grids characterized by bidirectional communication and decentralized energy generators (e.g., photovoltaics). Smart meters and energy management systems enable efficient control of energy flow.

IT Specialist Digital Networking

An IT profession focusing on the planning, implementation, and operation of networked systems. The activities include network design, system integration, data communication, IT security, and the connection of physical components to digital systems.

Practical Steps

1. Analyze the requirements for the networked infrastructure, taking into account the specific industry requirements. This forms the basis for successful system planning.
2. Design a network segmentation concept with clearly defined zones (LAN, DMZ, IoT network) based on security requirements and functionality.
3. Implement the network infrastructure with suitable switches, access points, and firewalls using VLANs to separate network areas.
4. Configure firewall rules based on the principle of least privilege to control traffic between zones.
5. Install and configure a monitoring system to monitor network performance, system availability, and security events.
6. Integrate IoT devices into the network using appropriate protocols (e.g., MQTT, CoAP) and implement separate security measures for these devices.
7. Set up a central logging system to collect all system events and make them available for later analysis.
8. Implement a backup concept for critical systems and data to ensure recoverability in case of failure.
9. Document the entire infrastructure, configuration, and processes for the operation and maintenance of the systems.
10. Test the entire infrastructure under real conditions and conduct penetration tests to identify security vulnerabilities.
